Commercial

Commercial buildings are buildings that are used for commercial purposes, and include office buildings, warehouses, and retail buildings (e.g. convenience stores, ‘big box’ stores, and shopping malls). In urban locations, a commercial building may combine functions, such as offices on levels 2-10, with retail on floor 1. When space allocated to multiple functions is significant, these buildings can be called multi-use.

Local authorities commonly maintain strict regulations on commercial zoning, and have the authority to designate any zoned area as such; a business must be located in a commercial area or area zoned at least partially for commerce.
